' Begin Constant Definition

' DB Configuration constants
' Fake const so we can use the MapPath to make it relative.
' After this, strictly used as if it were a Const.
Dim DB_CONNECTIONSTRING
DB_CONNECTIONSTRING = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.Mappath
("./db_scratch.mdb") & ";"
' We don't use these, but we could if we neeeded to.
'Const DB_USERNAME = "username"
'Const DB_PASSWORD = "password"

'Now we override the above settings to use our SQL server.
'Delete the following line to use the sample Access DB.
DB_CONNECTIONSTRING = Application("SQLConnString") & "UID=" & Application("SQLUsername")
& ";PWD=" & Application("SQLPassword") & ";"

' ADODB Constants
' You can find these in the adovbs.inc file
' Do a search for it and it should turn up somewhere on the server
' If you can't find it you can download our copy from here:
' http://www.asp101.com/samples/download/adovbs.inc
' It may not be the most recent copy so use it at your own risk.

Dim I ' Standard looping var

'We're going to keep this as simple as we can.
' 1. Create a Recordset object
' 2. Connect the Recordset to the table
' 3. Find the record to update
' 4. Update the record
' 5. Update the table
' 6. Close the Recordset

'Step 1:
Dim objRecordset
Set objRecordset = Server.CreateObject("ADODB.Recordset")

'Step 2:
' The syntax for the open command is
' recordset.Open Source, ActiveConnection, CursorType, LockType, Options
objRecordset.Open "scratch", DB_CONNECTIONSTRING, adOpenKeyset, adLockPessimistic, adCmdTable

objRecordset.CacheSize = 15 ' Cuts down on round trips to our SQL Server

'Step 3:
iRecordToUpdate = CLng(Request.QueryString("id"))

If iRecordToUpdate <> 0 Then
If Not objRecordset.EOF Then
objRecordset.MoveFirst
Do Until objRecordset.Fields("id") = iRecordToUpdate
objRecordset.MoveNext
Loop

'Step 4:
'Only update if they've told us to, o/w we never run this

' String / Text Data Type
objRecordset.Fields("text_field") = CStr(WeekdayName(WeekDay(Date())))

' Integer Data Type
objRecordset.Fields("integer_field") = CInt(Day(Now()))

' Date / Time Data Type
objRecordset.Fields("date_time_field") = Now()

'Step 5:
'Only update if they've told us to, o/w we never run this
objRecordset.Update

' Feel free to skip this area. (Ignore the man behind the curtain!)
